It's likely a browser extension interfering, please try in an Incognito window.

@dsky1990 It would be great if you can drop a link to the repo.

@reznord http://13.125.234.168:8080/wsh/build/index.html ,help to see it

@dsky1990 You do have an https error coming from the service worker refusing to register. I don't think this is causing the blank rendering, but you can preact build --no-sw to turn that off & look at the underlying problem.

[dsky1990]

@lukeed preact build --no-sw is not a right command

[developit]

@dsky1990 you're importing preact/debug twice (preact-cli does this for you).

The reason the screen blanks is because you have no default route, and no route is matching the current URL:

Notice that there are no routes in your <Router> that would match the URL:

You can see that this is the case if you pause when the page first loads, and change the URL to "/":

@developit thanks very much
